T0 all whom t may coneern.'

Be it known that We, JOHN W. 'J nnen and LAWSON W. WRIGHT, citizens of the United States, residing at Parkst-on, in the county of Hutchinson and State of South Dakota, have invented a certain new. useful. and lm proved Folding Convertible Gro-Cart and High Chair; and ive do hereby declare the following to be a full` clear, and exact description of the same, reference being had to the accompanving drawings, forming part of this sirieeification. and to the figures and letters of reference marked thereon.

This invention relates to improvements in appliances for facilitating and lightening the labor oi' attendingr and caring for children of tender age, the particular object of the invention being to provide a structure which may be folded into a small flat package, easilvs7 carried in one hand and capable of being quickly and conveniently converted into either a go-eart. in which the child may be trundled about, or into a high chair in which the child may be seated and held Withouty danger of falling or injury.

The invention consists in certain novel details of construction and combinations and arrangements of parts, all as will be hereinafter described and pointed out particularly in the appended claims.

Referring to the accon'xpanying drawingsfwFigure 1 is a side elevation of a structure with the main portions extended in full linesI to form a ehih'fs gri-cart and with certain of the parts in dotted lines in extended position to show the cover or top for the go-cart elevated and the frame extended to form the. legs of a childs` high chair; Fig. Q a section in a plane from front to rear otl the structure with the parts extended to form a ehilds high chair; some ot1 the parts being broken away in order that they may be shown on a large seule; Fig. il a bottom plan View of the structure with all o1" the parts folded so as to form a flat package for convenient` transportation; Fig. 4 is a, fragmentary section in a plane at right angles to the section of Fig. 2 with the parts in folded position. .many of the parts in this View being omitted to avoid confusion: Fig. 5 is r detail perspective vieu' of one o1" thc rear wheel frame brackets and a portion of one of the wheel frames or supporting arms; Fig. 6 is a detail fragnflentaqr :front elevation of a portion of the seat frame, showing one of the retaining hooks for a Wheel and leg frame; Fig. 7 is a detail sectional view showing two of the telescopic members with the locking device for holding 'them extended; Fig. 8 is a similar view showing the meeting ends of the telescopic/.wheel and leg frame members with the locking device for holdingr them against both longitudinal and rotary movement with relation to each other.

Similar letters ot' reference in the several figures indicate the sanie parts.

The structure of the present invention as illustrated in the drawings, embodies a seat frame A which may he conveniently formed of wood and preferably provided around its margin with a dependingr skirt within which the leg and wheel trames. together with the wheels themselves are adapted to fold, as shown in Fig. 3, when it is desired to form the structure into a convenient fiat package for transportation.

0n the under side of the seat frame A and near its rear portion there is pivotally mounted in brackets 71, a Wheel and leg frame, the two main members of which are formed of telescoping members B, B'. in the preferred construction the members P are directly pivoted in the brat-kots b and are connected rigidly together by diagonal cross bmces o', While the members B' are adapted to telescope into the members B and to be held in proper relation thereto when in either extended or in folded position. ln the preferred construction, automatic spring catches are provided in the Form of outwardly movable spring pressed pins (I, Fig. t?. which are adapted to enter openings r' in the members B. so as to hold the members against either relative longitudinal or angu lar motion. but said springpressed pins or catches (l artl adapted to be displaced or pressed inuardl)- b r the tinger of the attendant, so as to permit ot the relative movement of the parts'. whereby they may be shifted from one position to the other. The leg and wheel frames tortured bv the members B and l are adapted to he held in their folded position in Fig, 3, or in their extended posi tion, when the structure is used for a porambulator (Fig.I l) by catches or hooks D best seen in Fig. 6, mounted on the depending skirt at the front of the seat frame. Said wheel and leg frames. are, however, adapted to be held in their extended position, and at. the proper angle to the seat frame to form chair legs by diagonal braces formed of telescoping members B2 and B,

one pivotally connected with the Wheel and legr frames at 713 nd the other pivotally conneeted with the seat frame at b2, and these teleseoiiing men'ibers If and b3 are adapted to he held in their extended position by sprinrr pressed eatehes or pins E whieh may be of the eonstruetion showndin Fig. 7 and adapted to spring' out so as to prevent. Collapse ot' the leleseoi'iing members by engagement with the end ot' the member B2. Said spring' pressed catches or pins are, however. adapted to be foreed inwardly by the finger of the attendant when it' is desired to collapse thet parts.

The ends of the members li of the legir and wheel frame are Conveniently provided with knobs or rubber Cushions f, to form either the lloor eontaeting ends of they Chair legs or to prot eetthe ends of .the frames and prevent injury thereby when said frames are extended in the position shown in Fig. 1 for use. with the deviee as a perambulatm'. Said telescopic members B are also adapted to have rigidly connected therewith arms or brackets l", upon whieh the front wheels l" are joimnaled, and in the preferred Construction the arms are simply ybent at right angles to their body portions to form the spindles or journals for the Wheels, as will be readily understgiod` although it will be obvious that any ordinary arrangementy of wheel supportingr brackets may be substiv tuted for the arms ot the particular construction referred to.

To move the teleseoping members B' together, With the wheels carried thereby from the folded position shown in Fig. 3 to thel extended position shown in Figa-1, the retaining hooks D are released. said teleseoping members are given a quarter turn and are drawn outwardly until the wheels are in the position shown in Fig. l. and the hooks are then moved baek into engagement with said members on the inner Iside of the Wheel braekots.- The automatic eatehes (l will. when the Wheels are in this position be in operative engagement for loekingr the two teleseopie members against relative movement in any dirent ion, so that a substantially rigid running gear frame formed. and should it be desired to extend them to the position shown n dotted line in Vig. l, and in full lines in Fie; the `laid teleseoitiingf members l and wheels are given a quarter turn in the opposite direetion and the whole wheel and leer frame is turned down to the position stated. This nwn'ementr of the frame auton'n'ltirally extend, the diagonal teleseopingl braees formed by the members B2 and lt and the parts rre autmnatieally locked against eolapse until the automatic Catches are released .For cooperation vwith the lf when a chair to be developed from the formed by l the wheel and lefr trames betere referred ttf l structure, there is provided a second folding frame formed of telescopic members hinged or pivotally mounted on the under side of the seat frame near its forward edge- This. cooperating frame is formed of telescoping members G and (Y, the members Gr being pivotally mounted or hinged to brackets on the seat 'l'rame at y, and the said members (ir are rigidly eonuer'ted by diagonal braces g while the. members G Atoleseope into the members (i and are adapted to he held extended by spring catches or pins E corresponding to the spring catches or pins in the diagonal braces B2 B3 and shown in detail in Fig. 7.

l`he folding telescoping framel formed hy the members G and G are adapted to he held in their proper extended position for formingr the frontv legs of the chair by diagonal braces which substantially correspond to the diagonal braces formed by the members B2 and B". Thus. as shown, teleseoping members G2 and G are pivotally connected respectively with the ,frame G and rear portion ot' the seat frame, and are. adapted to be held extended by spring' catches E of the construction het'ore described.

Where, as is desirable in most instances, the perambnlator is to have four wheels, the seat frame is provided with pivot clips or braekets ll rigidly seeured thereto near its rear portion, and each of these clips H (see Fig. 5l haspivotally mounted in it a wheel supporting armor bracket H. Tn the general eonstruetion. the Wheel supporting arms of the brackets ll closely Correspond to the arms or brackets F of the forward wheels, that is to say, they may be bent at right angles lo form the wheel journals or spindles. 'lhey are. however. pivoally mounted in their supportingr eiips or braekets ll and are adapted to turn from the folded position shown in Fig. il down to the extended position shown in Figs. l and and to beheld in either position. as desired. by loeking pins h, whieh pass through openings zf in the elips or braekets` ll and Marriage the wheel supporting:y arms or braelwtll at points more or lessl remote trom their pivots. The pins l1 may "oiirenieutly he retained against. loss by bains or :'lniile wouw-:ions fr of ordinary vonstruetion.

The upper .side of the seat 'frame is provided with inwardlv folding! I--ide arms K, eaeh preferably ot taux-like formation open at the edLfe whirl; forms the top of the arm to eonr-titnte rerepmrles in whieh small arls a convenient means for accomplishing his end a folding or collapsible back board M may be hinged at its lower edge. between the folding;r arms K so asv to fold down flat upon the seat frame or to swing up to the position shown in full lines in Figs. 1 and 2. lVhen swung upto its operative position. this back hoard will of itself prevent the inward movement of the side arms, but as an additional precaution. straps la are secured to the upper outer sides of the arms and are adapted to he. drawn down and secured h v ordinary fasteningr devices b2 on the sides of the scat frame.. A strap N is adapted to be passed over thc front portions of the arms for retainingr the child in 'the seat.A and for supporting thc feet of the child, an extensible. trame() is mounted to slide toward and from the vfront edge of the seat frame and to carry a fabric or other suitable tiexihlc foot. rest 0.

A Ui-shaped handle is provided.- the, side arm standards of which are formed by telescopins: members l) ll adapted to beheld extended by spring,r catches y; corresponding to the catches ll heretofore described, and for holding this U-shaped Frame at the proper angle with relation to the lseat. frame, the men'ibers lf are pivotally connected at their lower ends to the side ot the scat-'traine and diagonal braces formed by telescoping members l"2 and P extend from the lower ends ot the members P to the, forward portion otl the seat. frame. The telescoping;` members l2 and Pi are 4held evtended by catches 7): correspon(ling;r to the catches E before described. and nal braces are ot' course` pivotally connected with the handle and seat frames respectively. In collapsing the handle. the catches ,fn and 712 are released, the members l and P collapsed or telescoped within each other.

and the vcollapsed handh`= is swung for wardly. thereby collapsingl the telescoping members l, l of the braces. the cross piece l" at the outer ends of the handle turningf down in' trout of the side arms to the position shown in dotted lines in Fig. l. and in full lines in Fig. Q.

A folding top formed with a flexibleI cover and the usual bows Q may bc hinged in side brackets Q on the .Seat trame. so a\y to swing from the position shown in t'ull linesy in Vig. l to that shown in dotted lines. and the said top may be held i`n its adjusted position by the known expedient of toothed segments formed by the upper edges ofthe bracllft--ts Q and adapted to receive pins (7 on the bow base when the top is swung,r up to the desired position.

For holdingl the back board M at. the dei inclination. a supporting strap 'M2 f be extended from one arm to the other lmound the rear side of the back board M and Where dcsiredpthis back board may t'ne ends of the diane-v fold down flat upon a pivoted seatI board M3, beneath which the seat frame may be cut away and provided with a closure M4, as will be readily understood.

In useit will be seen that when the parts are collapsed to the position shown in Figs. B and el, a substantially flat and relatively thin package is formed and the strap N may then serve to retain the arms and top firmly in folded position. while the wheel frames are retained in their folded position by Athe retaining' hooks and locking pins hereinbefore described. .Vith the parts in this folded position. the cross piece P of the handle may be utilized as a carr \in;1r handle the extension of the telescopii'ig members P, P when in folded position being;r prevented by the telescoping brace members P2 and P3 which are then full),7 collapsed a nd will not permit of distention of the members P, P'.

Then tbc parts are intended to form a high chairsthe wheels of the perambulator are all located between the leg frames in which position they ari: out of the way, and o ller no obstruction to t be passage of persons around the chair, so that the chair may then be utilized as an ordinaryhigh chair about the house, and t'or seating the child at table. but with thc capacity of being quickly and readily converted into a pcrambulator, or of beingl folded for transportation .when it is desired to take the child for airing under circumstances which may make it desirable to use a peraiul'uilator.

lt. will be noted that the frames which are hinged ttrtlie underside of the seatframe are composed ot divergent telescoping meinbers and the said trames arelgiinged at their narrow ends whereby. 'ivhenthey are folded in the position shown in Fig. 3, the outer telescopimgr members lie outside of the hinges of the opposite trame, thus permitting the parts to fold very coinpactly. This construction also in a large measure obviates any conflict with the bracket arms on which thel wheels are jonrnaled7 and inasmuch as the two hinged frames are substantially duplicates, it perfectly obvious that bot-h the fore and attv wheels may be mounted on the outer telcscoping members of the re spective frames. in fact., this construction may, under some circumstances, wand particularly to facilitate manufatlzture, be a prefcrred construction, and the appearance of i the rear wheels being simply attached to the tele-scoping members G', instead of to the seat trame. With this construction, when the frames are swune` downto form chair legs, the wheels should be turned reversely t a quarter or half turn as in the case of the t forward .vhecls. so as to lie between the ,l chair legs where they will be out; of the way.
